AUGUST W. OLSEN, OF PORTLAND, OREGON.

PNEUMATIC FLANGE-OILER FUR CAR-WHEELS.

Application filed October 23, 1914.

To all whom it may concern:

Be it known that I, AUGUST 7. OLSEN, a citizen of the United States, anda resident of Portland, Multnomah county, State of Oregon, have inventeda new and useful Improvement in Pneumatic F lange-Oilers for Car-WVheels, of which the following is a specification.

My invention relates to lubricating devices for oiling the flanges oflocomotive and car wheels, so as to eliminate the frictional resistanceimposed on the wheels while running on the curves of the track. It iswell known that the undue wear of the rails and of the flanges of thewheels, caused by such curves in the track is very considerable, andtherefore, is an important factor in the maintenance of railroadequipment.

One of the main objects of my invention is to provide automaticallycontrolled means for applying spray of lubricant to both sides of thecar wheel flange, both sides being oiled for the reason that both aresubjected to wear.

My invention further, has for its object the arranging of the lubricantapplying devices so as to apply the lubricant to the flanges of thewheels in the form of a spray.

I prefer to operate my device pneumatically, and to use as the operatingforce compressed air taken from the pressure tank of the air brakesystem.

My device is furthermore, so arranged as to be thrown into and out ofaction by con tact with lugs affixed to the rails near the ends ofthecurves in the trackway.

The details of my invention and its mode of operation are hereinafterfully described.

In the accompanying drawings, constituting a part of this specification,Figure 1, is a fraginental side elevation, showing one end of a railwaycar mounted on a standard truck, and my device is mounted on theequalizing bars of the latter. My device is shown as operativelyconnected with the air brake system pressure tank which is located underthe car. Fig. l is a sectional detail view taken approximately on theline A of Fig. 1, and illustrates the manner in which the supportingframe of my device is rendered vertically adjustable with respect to theequalizer bars on which it is mounted. Fig. 2, is a larger-scale sideelevation, show- Specification of Letters Patent.

This view shows the detail ofthe lugs and the manner in which they are aiiixed to the rails. Fig. 11,is a sectional view taken approximately on the line, 11-11, of Fig. 3.Fig. 12, is a plan view showing a detail of construction of one of theoil ejector element parts. Fig. 13, is a detail of the oil valve whichis contained in the oil ejector element shown in Figs. 3 and at. Fig.13, is a sectional view taken on the line CC, of Fig. 13; Fig. 14: is alarger sized view of the lower portion of the oil ejector element asillus trated in Fig. l; and Fig. 15 is a diagrammatic view showing asolenoid operated valve, the energizing circuit of which is adapted tobe closed by the relative displacement of the car and truck whenrounding a curve.

Referring in the first instance to Fig. 1, a, represents one end of astandard railway car mounted on standard running gear comprising a truckframe, 7), having journal boxes, 0, in which are journaled the axles offlanged ca r-wheels, c. f, represents the equalizing bars of the truckframe, and (Z, (Z, represents a section of the track rails upon whichthe car is adapted to travel, and in this view the car is presumed to betraveling to the right, as indicated by the arrow, F.

My device is mounted on the equalizing bars, 7', because there is nosubstantial vibration of these parts relative to the rails, and in orderto keep the operating members of my device in substantially constantposition with respect to the abutment lugs provided on the track. Sincethe wheels, 0, become worn in service and are periodically sent to theshop to be turned down to a smaller diameter, it is desirable that mydevice be adjustably mounted with respect to the equalizing bars so thatthey may be adjusted to the right height above the track. Thisadjustment is made possible by mounting my device on supporting bars,'5, extending longitudinally with the equalizer bars, 7'. Said bars, 2',are supported at their ends on cross-bars, 7a., the latter extendingtransversely between the equalizing bars, Setscrews, 72,, adjustablyspace the bars, it, above the bars, f. The bent down portions, it areprovided with slots, 71. by means of which the bars 71,, are rigidlybolted to the equalizing bars, The bolts 72., must be loosened when anyadjustment is to be made.

0, represents a pressure air-tank of the usual air-brake system. Fromsuch tank extends an air-pipe, e, which conducts the air to theair-brakes, (the latter not being shown in the drawings). The oilejector element of my device is connected with the pipe, 6, by a directpipe line t.

In the pipe, t, is a cut-off valve t, and a spring-controlled valve, 25,the latter being normally closed. Said valve t is of the whistle-valvetype and includes an arm, t, connected to the fulcrumed lever-arm, t",the latter being connected by a link i to a crank-arm, 7*, which isfixed on the parallel shaft Z. See Figs. 2 and 6. The shafts Z, Z, arejournaled in the gearbox, y', and are connected by the reversing gears,Z, k as shown in Fig. 7. On the outer extremities of the shafts, Z, Z,are rigidly mounted the slotted crank arms, 0, 0. The pendent arms, 79,7) loosely mounted on the ends of shafts Z, Z, adjacent the slottedarms, 0, 0, respectively, are held against longitudinal displacement bymeans of collars Q, Q. hilounted on the inner extremities of the shafts,Z, Z, are brake springs, a, n, the compression of which is adjusted bylock-nuts, m, m. Said brake springs 11, n, serve to hold the shafts,

Z, Z, in any position to.which they are rotated and eliminate vibrationafter such rotation is completed.

On the rails, (Z, (Z, of the curved track portion, are mounted abutmentlugs, g, g, respectively, as shown in Fig. 9. The con struction of saidlugs and the way in which they are bolted to the rails are shown in Fig.10. v

The parts thus far described relate to the means for automaticallythrowing my device into action when the car is approaching a curve andout of action when the car passes out of said curve. The operation ofthese parts will be described hereinafter.

I will now describe the pneumatic oil ejecting element, 8, theconstruction of which is fully shown in Figs. 3, 4 and 11 to 14C,inclusive. Said oil ejecting element is connected at its lower end tothe pressure tank, a, and at its upper end to an oil supply tank When inoperative state, the compressed air is adapted to intermix with the oilin a chamber provided in said oil ejecting element, and blow theatomized mixture, in the form of a spray, to the wheel flanges. For thepurpose of insuring a positive feed of the oil to said chamber, 1subject the oil to a fluid pressure through the pipe,

The construction of the oil ejecting element is as follows: In the lowerend of the element is a piston chamber, u, directly connected by thepipes, t, and c, with the compressed air tank, a. In the piston chamber,20, is a piston, u", the reciprocation of which is guided by a stem, u,adapted to slide in a vertical bore in the top of said chamber. Thepiston, a is normally held in its down position by a compression coilspring, a". A bolt, 10, is adjustable in the stem of the piston, asillustrated in Fig. 14-, and provides a means for lifting the oil valve,2 a greater or lesser degree by the reciprocation of said piston, asdesired.

The piston chamber, a, is connected by the ducts, 10 with theintermixing chamber, 'w, and said ducts are closed by the piston, if,when the latter is in its down position. See Fig. 14. Mere pressure on abody of oil contained in a tank, the latter having a discharge conduit,would not be satisfactory, because the oil is toothick. The oil,therefore, must first be atomized. This is the function of the mixingchamber, Ll. Into this chamber the oil is permitted to flow by gravityor pneumatic pressure from the oil tank 2, and the compressed air isalso admitted to this chamber through the ducts, w The admission of thecompressed air slightly in advance of the oil is preferable in orderthat the body of oil admitted into the mixing chamber, 10, will beimmediately atomized. Likewise, the inflow of oil into said chamber, 10,is checked slightly in advance of the checking of the compressed aircurrents so as to keep the discharge conduits clear when the device isin inactive state.

In the event that steam was to be used instead of compressed air, thepipe, t, would have to be connected with some convenient type of steamgenerator, into the details of which it is not necessary to go.

The mixing chamber, w, is connected by a bore 50', with an oil chamber,50. A puppetvalve, y, is adapted to seat on the upper end of the bore r,so as to cut off the flow of oil into the chamber, to. Said valve isprovided on its lower end with guide VaneS, 3 adapted to slide in thebore, a2. Furthermore, a centrally located lug, 3 is provided on thelower portion of the vanes, f, such lug being located in verticalalinement with the bolt, 1Z3. The puppet valve, y, is further providedwith a stem, y", and a compression spring, 3 is coiled around the stemof the valve, 3 said stem, 3 being adapted to be reciprocated in thevalve stem guide, 3. The guide, 3, is supported centrally above thechamber, :0, by the spokes, it. See Fig. 12. The oil chamber, 00, isconnected directly with the pipe, 2', through the open spaces betweenthe spokes, a, and said pipe, 2, connects with the oil reservoir tank,a.

In the pipe, 2, is a cut-off valve, 2- The mixing chamber, 10, haslateral outlets w (compare Figs. 4 and 11) to which are connected thepipes, 2, through which the ejected oil is conducted to the wheelflanges. The pipes, 2, extend to each side of the truck, and at theirextremities they have bifurcated nozzles, 6, arranged to divide the flowof oil into two sprays discharging against the opposite faces of thewheel fiange as shown in F ig. 5. Furthermore, the ducts, 10 areprovided with adjustable needle valves, 7, so as to regulate thestrength of the compressed air currents.

The slotted crank arms, 0, 0, are positioned reversely with respect toeach other, (see Fig. 6). The pendent arms .7 10, are each provided withstud-pins, p engaging with the slots, 0 of the crank arms, 0, 0, andeach arm 79, 79, has an idling movement in one direction, the length ofthe slot, but engage with and rotate their related crank arm 0, 0. andthereby the shafts, Z, Z, when moved in an opposite direction.

Suppose now that the car is traveling in the right hand direction overthe curve in the track, as shown in Fig. .9. The pendent arm, 79, andcrank arm 0, are located as shown in the full lines of Figs. 6 and 8.hen the arm, 79, strikes the lug, g, the former will be thrownclockwise. The studpin, p being located at the left end of the slot, 0will cause the crank arm, 0 and therewith the shaft, Z, to be alsorotated clockwise, and the consequent throw of the arm, 1', will,through its linked connection with the valve, 6 open the latter.C0mpressed air will in consequence be admitted through the pipe, t, intothe bottom of the piston chamber, a, lifting the piston, M2, and in sodoing uncovering the inlet ports of the ducts, 10 leading into the oiland air mixing chamber, w. Simultaneously the bolt, M of the piston, astrikes the lug of the puppet valve, 1 and by lifting the latter,permits oil to flow down into the mixing chamber, 10, from whence theoil is then expelled by the air pressure through the pipes, 52, and outof the nozzles, 6, by which t 1s sprayed against the opposite faces ofthe flanges of the wheels as mentioned. The piston, u will furthermoreseatitself in the upper end of the chamber, a, so as to close the guidebore in which the stem of the piston slides. As soon as the car hastraveled forward a short distance so as to bring the pendent arm, 2),past the abutment-lug, g, the former will drop back into pendentposition, leaving the parts positioned as shown in the broken lines ofFig. 8. The rotation of the arm, 7), will cause the reverse rotation ofthe arm, 7), through the medium of the gears, 76, Z1, and the crank arm,0 will now be positioned as the crank arm, 0, was in the first place.The passage of the car from the curve will next cause the pendent arm,72, to strike the lug, g, on the rail, (Z, and thereby cause a reversalof the action previously described, thereby restoring all parts to theirnormal position. This action closes the valve 2., and places the oilejecting element, .9, in its inactive state.

An auxiliary feature of my system is the providing of an independentmeans of con trol, operable from the cab of the car or any otherconvenient location, which may be thrown into active state,independently of the automatic devices. This separate control consistsof a pipe, 14, which bypasses the fluid under pressure from the conduit,6', to the conduit, 25, around the uilve, t and in which is a handoperated valve a conveniently located so as to be accessible to theoperator. In this way, the flanges may be oiled at any time,independently of the automatic actuating means.

In Fig. 6, I have shown an alternate construction for operating thevalve in the pipe, 6, when the shaft, Z*, is rotated. This constructionconsists in making the shaft, Z*, a cam-shaft, which is done by fixing acam. Z thereon, lowering the conduit, 2?, and using the valve, t insteadof the valve, 25

The contact lugs for operating the pendent arms, 79, 77, could, ofcourse, be fixed either on the rails or the ties adjacent to the rails.abutments could also be so arranged as to be located on one side of thetrack only, instead of on both sides.

In Fig. 15 I show diagrammatically an electrical means for operating thevalve Undoubtedly these arms and contact which controls the flow offluidunder pressure through the conduit, 2?. In this case, I use a solenoidoperated valve, 20, of the well known commercial form, electricallyconnected through the generator, 19. Spring controlled switches, 17 and18, normally open, are mounted on the under side of the car floor, andthe circuit of the solenoid operated valve, 20, will be closed by theclosure of either switch. A switch operating member, 16, is rigidlyfixed on the truck of the car, and whenever the car runs on a curve, therelative movement between the car body and the truck, will cause themember, 16, to bear against and close one of the switches, 17 or 18,depending on the direction of the curve. This action will open thevalve, 20, and cause the oil to be discharged to the wheel flanges inthe manner previously described.

As soon as the car passes onto a straight stretch of track, the car bodyand trucks will resume normal position, and the circuit of the solenoidoperated valve, 20, will be broken, thereby allowing said valve to closeand as a consequence, replacing all parts to their inactive state.
